Snyk has created this PR to fix 2 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

  • code/frameworks/server-webpack5/package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning
Failed to update the yarn.lock, please update manually before merging.

Code Review

This pull request, automatically generated by Snyk, aims to resolve security vulnerabilities by changing the version of @storybook/builder-webpack5. However, the proposed change from a workspace:* reference to a pinned version (7.1.0) is problematic in this monorepo context. This constitutes a major version downgrade from the version present in the workspace (8.3.0-beta.3) and is highly likely to introduce breaking changes or build failures. I've recommended reverting this change and suggest addressing the vulnerability by updating dependencies within the workspace directly.

critical

This change from workspace:* to a pinned version 7.1.0 is incorrect for a monorepo setup. It breaks the workspace protocol, which intends to use the local version of @storybook/builder-webpack5 (version 8.3.0-beta.3 in this workspace).

Pinning to 7.1.0 is a major version downgrade and will likely introduce breaking changes and build failures. The correct approach to fix the underlying security vulnerability is to update the dependencies of the @storybook/builder-webpack5 package within this monorepo and then update the lockfile, rather than pinning to an old, external version.

"@storybook/builder-webpack5": "7.1.0",
"@storybook/builder-webpack5": "workspace:*",
